XGATE activity can still be compared, traced and can be used to generate a breakpoint to the XGATE
module. When the CPU enters active BDM mode through a BACKGROUND command, with the DBG
module armed, the DBG remains armed.
The DBG module tracing is disabled if the MCU is secure. Breakpoints can however still be generated if
the MCU is secure.

The DBG sub-module features two external tag input signals (see
(DUG) for the mapping of these signals to device pins. These tag pins may be used for the external tagging
in emulation modes only
